PURPOSE: A holding door panel window coupling structure is provided to secure simple and firm coupling of a window frame to a window hole of a holding door panel without fasteners. CONSTITUTION: A holding door window(20) is implemented by fitting front and rear window frames(21,22) to a window hole bored in a holding door panel. The front and rear window frames include a front frame(23) and a protruding section(24) which is formed on the inner side of the front frame to place a transparent window. A coupling hole(26) with a fitting protrusion(25) is formed in the protruding section of the front window frame. A coupling piece with a coupling projection(27) is formed in the corresponding protruding section of the rear window frame and inserted into the coupling hole and caught on the fitting protrusion. |
